Abstract

Herein are disclosed methods and assemblies for mounting an article to a surface by a double-faced adhesive. At least one spacer is used that is deflectable upon the application of sufficient force. When in a first, undeflected condition, the spacer provides sufficient space between the mounting surface and the double-faced adhesive such that the double-faced adhesive does not contact the mounting surface, thus the position of the article can be adjusted. When in a second, deflected condition, the spacer allows the double-faced adhesive to contact the mounting surface such that a bond can be established between the double-faced adhesive and the mounting surface.

Claims

1. An assembly for attaching an article to a mounting surface, comprising:

an article comprising at least one bonding surface;

at least one double-faced adhesive with first and second oppositely-facing major adhesive surfaces, with the first major adhesive surface being adhesively bonded to the bonding surface of the article;

at least one deflectable spacer arranged on the article;

wherein the spacer is deflectable at least from a first, undeflected condition to a second, deflected condition,

wherein when the spacer is in the first, undeflected condition at least a portion of the deflectable spacer extends outward from the article past the second major adhesive surface of the double-faced adhesive, and

wherein when the spacer is in the second, deflected condition, no portion of the deflectable spacer extends outward from the article past the second major adhesive surface of the double-faced adhesive.

2. The article of claim 1 wherein the deflectable spacer is chosen from the group consisting of a compressible foam, a compressible nonwoven, a compressible coiled spring, and a compressible leaf spring.

3. The article of claim 1 wherein the deflectable spacer is a removable clip that when in its first, undeflected condition is mechanically attached to the article.

4. The article of claim 1 wherein the deflectable spacer is a breakable clip that when in its first, undeflected condition is mechanically attached to the article.

5. The article of claim 1 wherein the article comprises at least one mounting plate connected thereto and comprising the bonding surface of the article, wherein the piece of double-faced adhesive is attached to the bonding surface of the mounting plate, and, wherein when in the first, undeflected condition, the deflectable spacer is attached to the mounting plate.

6. The article of claim 1 wherein the double-faced adhesive is a stretch release adhesive.
